Was she born this way or does Lady Gaga just enjoy dressing up like a man? Last week, Mother Monster brought back her male alter ego, Jo Calderone, when she unveiled the cover of her new single, "You and I." Gaga tweeted the artwork over the weekend, writing: "You will never find what you are looking for in love, if you don't love yourself." Calderone has made appearances before. In September 2010, Nick Knight photographed him for Vogue Hommes Japan, and Jo revealed in an interview that he is from Palermo, Sicily, works as an auto mechanic, and owns a "bunch of muscle cars." And what does he think of Lady Gaga? "She's f--ckin' beautiful and funny and interesting."

In the mid-'60s, Bob Dylan was accused of misogyny for his ballad of feminine strength and vulnerability "Just Like a Woman." But 40 years later, it took a woman to capture Dylan in all his awkward glory in Todd Haynes' biographical character study I'm Not There. As one of six actors portraying the legendary singer-songwriter, Cate Blanchett was so eerily convincing that Anthony DeCurtis, reviewing the film, wrote: "It's hard to imagine that any male actor, or any less-gifted female actor for that matter, could have lent such rich texture to the role." The cross-dressing performance earned Blanchett an Oscar nomination and Golden Globe Award—for Best Supporting Actress.
